Last month, I called for the World Bank to be led by a global development leader rather than a banker or political insider. “The Bank needs an accomplished professional who is ready to tackle the great challenges of sustainable development from day one,” I wrote. Now that US President Barack Obama has nominated Jim Kim for the post, the world will get just that: a superb development leader.

Obama has shown real leadership with this appointment. He has put development at the forefront, saying explicitly, “It’s time for a development professional to lead the world's largest development agency.”

Kim’s appointment is a breakthrough for the World Bank, which I hope will extend to other global institutions as well. Until now, the United States had been given a kind of carte blanche to nominate anyone it wanted to the World Bank presidency. That is how the Bank ended up with several inappropriate leaders, including several bankers and political insiders who lacked the knowledge and interest to lead the fight against poverty. FULL POST

A famous claim in economics is that the cost of services (such as health care and education) tends to increase relative to the cost of goods (such as food, oil, and machinery). This seems right: people around the world can barely afford the rising health-care and school-tuition costs they currently face – costs that seem to increase each year faster than overall inflation. But a sharp decline in the costs of health care, education, and other services is now possible, thanks to the ongoing information and communications technology (ICT) revolution.

The cost of services compared to the cost of goods depends on productivity. If farmers become much better at growing food while teachers become little better at teaching kids, the cost of food will tend to fall relative to the cost of education. Moreover, the proportion of the population engaged in farming will tend to fall, since fewer farmers are needed to feed the entire country. FULL POST

We live in a time of high anxiety. Despite the world’s unprecedented total wealth, there is vast insecurity, unrest, and dissatisfaction. In the United States, a large majority of Americans believe that the country is “on the wrong track.” Pessimism has soared. The same is true in many other places.
Against this backdrop, the time has come to reconsider the basic sources of happiness in our economic life. The relentless pursuit of higher income is leading to unprecedented inequality and anxiety, rather than to greater happiness and life satisfaction. Economic progress is important and can greatly improve the quality of life, but only if it is pursued in line with other goals. FULL POST
